This paper presents the effects of various parameters of fabricated electro chemical micro machining (ECMM) setup on machining response characteristics during micro drilling of Hybrid Al/(Al2O3p+SiCp+Cp)-MMC. AnECMM setup has beendesigned and fabricatedfor the purpose. Fabricated ECMM setup has different units such as mechanical machine unit, electrical power supply and control unit, electrolyt...

Ultrasonic bonding has an increasing application in the micro assembly of polymeric micro-electro mechanical systems (MEMS) with high requirements for fusion precision. In the ultrasonic bonding process, the propagation of ultrasonic vibration in polymer components is related to the interfacial fusion, which can be used as a monitoring parameter to control ultrasonic energy. To study the vibrat...

We show that chemical fixation enables top-down micro-machining of large periodic 3D arrays of protein-encapsulated magnetic nanoparticles (NPs) without loss of order. We machined 3D micro-cubes containing a superlattice of NPs by means of focused ion beam etching, integrated an individual micro-cube to a thin-film coplanar waveguide and measured the resonant microwave response. Our work repres...

Abstract Ultrasonic additive manufacturing (UAM) is a solid-state metal process, with the combination of layer by ultrasonic seam welding and CNC machining. Due to friction deformation at bonding interface, softening effect temperature generated, microstructure substrate materials evolving constantly. In this paper, in order better understand mechanisms, good practice capability UAM, influence ...

magnetic abrasive finishing (maf) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. in this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of al2...

Organic micro-pollutants accumulate to a certain extent in sewage sludge and are therefore ecologically relevant if the sludge is to be reused in both agriculture and landscaping applications. This paper describes the degradation of endocrine-disrupting compounds and other micro-contaminants by means of ozone and ultrasonic treatment. One of the findings is that, as expected, aromatic compounds...
